Effects of Sintering Temperature on the Morphology and Photoluminescence of Eu3+ Doped Zinc Molybdenum Oxide Hydrate

Synthesis of shape controlled and rare-earth doped ZnMoO 4 nanostructures on a large scale with low costs is a present challenge in nanotechnology. The precursor of Eu 3+ doped zinc molybdenum oxide hydrate (Zn 5 Mo 2 O 11 ·5H 2 O) was synthesized at room temperature via the coprecipitation method. The influences of the sintering temperature on the microstructures and photoluminescence (PL) of the precursor were investigated by means of X-ray diffraction, scanning electron microscopy, thermal gravimetry, differential scanning calorimetry, energy dispersive X-ray spectroscopy, diffuse reflectance spectroscopy, and PL spectrophotometry. It is found that Eu 3+ doped ZnMoO 4 nanostructures can be derived by sintering the precursor at a relatively low temperature of about 400°C. Our results have demonstrated that Eu 3+ doped ZnMoO 4 nanostructures can be cost-effectively derived by sintering the precursor at a relatively low temperature.
